NMI purple diagnostic screen on HPE ProLiant Gen8 servers
It seems, there is an issue on HPE G8 servers with the below ESXi versions:
- ESXi 5.5 Patch 10
- ESXi 6.0 Patch 4
- ESXi 6.5
Intel® IOMMU’s (aka VT-d) interrupt remapper functionality has been changed in the above versions and you need to enable it manually:
- Run this command:
esxcli system settings kernel set –setting=iovDisableIR -v FALSE
- Reboot the ESXi host.
- Ensure the iovDisableIR setting is set to FALSE with this command:
esxcli system settings kernel list -o iovDisableIR
For example:
esxcli system settings kernel list -o iovDisableIR
